GXP · OPEN

Payments

A gateway is the one product where “mostly works” is not a state you are allowed to ship in.

GxPay

Fintech payment gateway. I build and maintain the product and the payment infrastructure under it. Customer-facing and internal applications, the APIs between them, authentication, real-time functionality, and the production workflows that keep all of it upright.

Role: Fullstack Software Engineer
Period: Jun 2026 – present
Surface: Customer app · internal tooling · APIs
Stack: Node.js · React · TypeScript · REST

MYH · DELIVERED

Four apps.

Public site, admin dashboard, sales and analytics dashboard, blog. One component system under all four.

MYHOTCAKE

Provider–client marketplace. One frontend owner, four surfaces. That only works because they share parts. Shipped into it: messaging, blacklisting, content feeds, premium media workflows, posts, referrals, retention and KPI tracking, and live reporting.

TPU · DELIVERED

13,000+

Daily active users on the Vue and React applications, through a migration to Nuxt.

Top Universe

Applications at daily scale. The Vue.js and React applications here served 13,000+ people a day. I maintained them, then supported the migration off a legacy codebase onto Nuxt.js. SEO performance and maintainability both improved: the unglamorous half of the job, and the half that mattered.
